Unam Pumas extended their lead at the top of the Mexican Clausura as they claimed a 1-0 win at ten-man Necaxa.

Unam made the most of Everaldo Barbosa's 52nd-minute red card by grabbing a late winner through substitute Juan Carlos Cacho.

The win puts them six points clear of Tigres Monterrey, although they have played a game more than their rivals.

Necaxa remain one place off the foot of the standings.
